Yes, even on our local lake, winds topped 50mph... I was outside seconds before the storms hit in Scranton, PA... in Nay Aug Park actually... watching the classic Beaufort scale indicator, a flag! Wife knows a am a huge advocate of knowing winds by indicators... and I watched, and had her and my daughter watching with me as I said, look, that's 15, thats 25, that's 30... LOOK! 40mph, 50mph and 40mph... back and forth. I was told it peaked to 60mph, but I can't agree with it. The flag was nearly bending the pole down, with it nearly ripping off it's halyard.
We were in the car at that point, storm came up STUPID quick... of course we knew it was coming, but not how bad it'd be. We spent the next hour dodging downed trees, driving home.
A friend of mine was up on our local lake, and he got some pretty darned impressive footage of the squall line. He also verified winds topping to 60... The video doesn't show the indicators he saw, because he didn't video it until after he saw the initial spike of wind. I'll see if I can get him to post the vid publicly.
This storm line caused a significant amount of damage, and indicators of a low grade tornado in one of our northern counties.
